Ventec AOV SCD LDN 0.6m2 GFA Automatic Smoke Damper
The Ventec SCD LDN Smoke Control Damper has been developed for use in smoke control systems serving multi-storey buildings for both domestic and commercial smoke shafts. These shafts can be dry wall or masonry/ concrete construction. \n \nThe lobby damper assembly consists of two parts; damper and grille. The main sleeved damper with peripheral flange allows it to be fitted flush into the builders aperture. A 24V power open/power closed actuator is used to drive the damper blades from the normal closed position to the fully open position. All damper internal surfaces are spray painted matt black to allow discreet installation behind the supplied aesthetic grille.
